Answer: Fireworks exploding is a chemical change.
Explanation: Lighting gunpowder, and making the explosion is a chemical change.
Isotope 1: 89.905 * 51.45 = 4625.61225 / 100 = 46.2561225
Isotope 2: 90.906 * 11.22 = 1019.96532 / 100 = 10.1996532
Isotope 3: 91.905 * 17.15 = 1576.17175 / 100 = 15.7617075
Isotope 4: 93.906 * 17.38 = 1632.08628 / 100 = 16.3208628
Isotope 5: 95.908 * 2.08 = 268.5424 / 100 = 2.685424
46.2561225 + 10.1996532 + 15.7617075 + 16.3208628 + 2.685424 = 91.22377
actual mass Zr = about 91.22
Destroying the wetlands will reduce the bay's water quality and vegetation will not grow effectively near bay as a result of which ecosystem will also destroy.
<h3>What is ecosystem?</h3>
All species and the physical environment with which they interact make up an ecosystem.
- Nutrient cycles and energy flows bind these biotic and abiotic components together.
- Photosynthesis brings energy into the system, which is absorbed into plant tissue.
As it is already mentioned that, water of the wetlands was carry nutrients which in turn was taken up by plants and vegetation, and if it will destroyed near a bay then the vegetation of that place will destroy as they will not get proper nutrients, which in turn also affects the ecosystem.
Hence destroying the wetlands will reduce the bay's water quality and vegetation will not grow effectively near bay as a result of which ecosystem will also destroy.

Answer:
The amount of CaCl2 produced depends on the amount of HCl in the reaction.
Explanation:
The amount of HCl is used completelyin the reaction unlike CaCO3 which remains after reaction.
Answer:The heat source for our planet is the sun. Energy from the sun is transferred through space and through the earth's atmosphere to the earth's surface.
